To all whom may concern:

Be it known that 1, JOHN H Bonnnonnns, s citizen of the United Stilt-cs, residing at Ashla-nd, in the county of Ashls-nd and State of, Ghio have invented s new useful Traci; or Sliding Doors, the follow ing 1 specification My nrention relates to improvements in racks for sliding doors, in which the track is of tubular form and made in comparatively short sections, and adopted to be supported by suitable brackets to make a track stony desired length, upon which the door hangers for supporting the sliding door may travel; and the objects oi my improvement ere first to provide s strong' and substantial traclr which will be light and of inexpensive construction;, second, to provide a track which may be easily handled in manufactur mg, packing and shipping and may be stored in comparatively small space; and third, to

provide a track which may be easily erected, may be made of any length desired end when in use will prove strong, substantial and not easily diserrenged.

l attain these objects by the constructionillustrated in the accompanying drawing, in which- 1 Figure 1 is a front elevation of three sections of track and brackets therefor as essembled when erected upon c building. Fig. 2 is a topview of the some. Fig. 3 is a per spective View of one of the center brackets. Fig, 4 is a perspective View of a section of split track, the said View showing e portion of the track broken sway. Fig. 5 is a pers active View of one of the *id brackets.

'ig. 6 is a perspective View of a section of unsplit track one end of said section attached to an end bracket and a portion of seid seetion broken sway to disclose the not that said section is not split, this form of section 2. Diemetrioolly opposite thessid'opening and at each end of the section is the slot 3 which extends for a distance from the en of'the sect on equal to half the width of the Specification oi Letters Patent.

Application filed May 1%, 1905 Serial No. 432,778.

supporting portion of the center bracket hereinafter to be described and of a width equal to the thickness of said supporting portion.

i is base portion of the center bracket, said base portion being provided with the holes 5, for the purpose of alhxing the'braokot to the side of the building by means of screws. or bolts 'lhesaid base portion is extended into the shoulder 6 and extending beyond said shoulder end-integral therewith is-t-he supporting portion 7'. The supporting portion is likewise integral with the head 8,

which produces a, second shoulder at th' point 9, the distance between the shoulders 6 and 9 being equal to the external diameter of the tubular track sections, the thickness of the supporting portion 7 being such as will permit of its being readily seated in thelongitudinal opening 2, and the slot 3, end the width thereo being twice the length of the slot 3.

The end bracket is provided with the base 10, in which are arranged holes 11 for the purpose of affixing the bracket to the side of a building as in the case of the center brackets. Arising from the base portion 10 and integral therewith is the frame portion, which is preferably of the rectangular form shown and composed of the parallel lateral extensions 12, and the connecting portioni lB. The track supporting portion 14 extends between the base 10 andthe portion 13 and,

is integral therewith. The said portionfl l' is of a thickness such as maybereadilyseated in the opening 2 end the slot 3 and is adapted to receive the some in the erection of the truck. Upon the portion 14 is formed the enlargement 15, adapted to engage the track nlong'the external edges of the longitudinal opening 2, to hold the track rigidly in lace upon the support 14, and between sai en largement and the vertical portion 13.

1n the modification shown in Fig. 6, the

tubular track section 16 is made of'a 'cornplete or unsplit tube and does not have the longitudinal opening 2 shown in the'seotions 1. The section 16 is provided with the slot 3 as'in the case of sections 1, and also with a diametrically opposite slot 17 of the same form and dimensions, adapted to take the piece of the end of the o ening 2 in the sections 1. As will be readi seen thesame center brackets and end brackets may be used with sections similar to the sections 16,

the only modification being the omission of the longitudinal opening 13.

In the erection of the track for use upon a building an end bracket is screwed to the side of the said building. A scctionof track isthen arranged upon the track support, H, the slot 3 and the opening 2 being placed over the supporting portion 14 and the section moved longitudinally upon said portion until the end of the slot 3 is reached, the enlargement 15 and the vertical portion 13 will aid in holding the end of the track rigidly in position. A center bracket is then arranged with the supporting portion 7 extending through the opening 2 and the slot 3, theshoulders 6 and d maintaining the end of the section firmly in position upon said brackets-rid the slot 3 permitting the supporting portion to be. engaged for half of its width. Another section is then arranged with one end supported by the bracket and a second bracket is arranged in a similar manner at the other end of the second section. This process of erection is continued until the desired length of track has been provided at which point the other end bracket is arranged upon the end of the last section and fastened to-the wall of the building. It will be understood that the sections thus arranged and supported end to end will form a continuous track upon which a door hanger may freely move from end to end, and the rectangular frame on the end brackets will provide a substantial and prac tical end stop to prevent the said hanger from running off the end of the track. The sections being abuttod end to end upon the center brackets there can be no longitudinal disdlaccinent ofthe said sections and the end bracket beingbraced against longitudinal strain by reason of its construction will aid in the maintenance of rigidity. The sections are prevented from moving transversely either in a horizontal or vertical plane by reason of the construction of the slots, openings, supporting portions, shoulders, heads, enlargements and vertical por tions as hereinbefore described, and it wilibe seen that all of the objects above set forth are thus fully attained.

Having fully described my invention. what I claim as new and desire to secure by Letters Patent, is

1. The herein described track for sliding doors comprising sections of tubular track, each section provided with a longitudinal opening nd a slot at each end opposite from said opening, center brackets, each bracket provided with base portion, supporting portion and shoulders, and end brackets, each end bracket provided with basemnrtion,

sup orting portion, and frame portion, the sai track ortions adapted for engagement at their e11 s with the supporting portions of the said brackets, and means for attaching said brackets to the side of a building.

I 2. A track for sliding doors of the class described, comprising end brackets, provided with frame portions and supporting portions and enlargements thereon, tubular track sections provided with longitudinal openings and slots at the ends of said sections and center brackets provided with base portions, supporting portions and shoulders, the said track sections adapted for engagement with the said supporting portions by means of said longitudinal openings and slots, substantially as and for the purpose specified.

3. In a track for sliding doors, a tubular track section provided with substantially diametrically opposite end openings in the walls thereof, and means comprising brackets extending through said openings, wherebysaid sections are supported and held in rigid alinement,substantially as and for the purpose specified.

4. In a track for sliding doors, an end bracket provided with a base portion, frame portion and a supporting portion extending between said base portion and said frame portion, the said supporting portion having an enlargement, ad means for attaching said bracket to the side'of a building, substantially as described.

5. In a track for sliding doors, a tubular track section provided with oppositely disposed alined slots, a center bracket provided with a base portion, a supporting portion adapted to extend transversely through said slots, shoulders arranged on said supporting portion, and means for attaching said bracket to the side of a building, substantially as described.

6. In a track for sliding doors, tubular track sections provided with substantially diametrically opposite slots and brackets for supporting said sections, said brackets extending transversely throu h said sections and through said slots, sai brackets being provided with means for preventing the said sections from becoming disenga ed from said supporting bracket substantia ly as and for the purpose rpeciiied.

In testimony that I claim the above, I have hereunto subscribedmy name in the presence of two witnesses.
